When you pass along someone’s secret, the only thing everyone actually learns is that you can’t hold one.

Passing on a secret says more about you than about the secret. Whatever was revealed will fade, but everyone present has just learned how you handle something you were trusted with, and that is what they remember when deciding what to tell you. The cost falls on you, not on the story.

When something arrives marked private, let it stop with you, including in the version where you tell only one person. A reputation people can rely on is built exactly here, in moments nobody will ever congratulate you for. Say nothing, and let that be what you are known for.
